Ok... I got this weber off of a buddy who had it sitting on an old truck that barely ran.  Anyways He says that he doesn't think that both barrels were working.  Well I am getting ready to buy a rebuild kit and a new filter when I noticed that there is like a diaphram looking thing on one side and right opposite it is an area that looks like it used to have another diaphram that attached via 4 small bolts.  Does anybody have any close up pics of there carb so that I can compare?  PLease HELP.  oh yeah it is a 32/36 DFAV.
Thanks
      
                        
                      
                             
      
            
            
        if the carb is on the motor which side has the missing piece? if its the passenger side it may have been the plug for the electric choke
      
                        
                      
                             
      
            
            
        if it's an dfav then it has a water choke...."a" denotes water (agua), "e" for (electric).
